Research on Reuse and Quality of Domestic Wastewater Treated by the Submerged Membrane Bioreactor

The problem about usable water in many cities becomes more and more imperious. The reuse of domestic wastewater is a good way to solve the problem. This paper deals with the reuse and quality of domestic wastewater treated by the submerged membrane bioreactor. The pilot-scale test indicates that the system can run steadily and outflow quality is better than that of water for domestic reuse stated by the Ministry of Construction. The treated water can be used in irrigating lawn and washing closets and cars, which is beneficial to the development of environment,economy and society.
